Hello,
You can also use MetaPost to render math stackers, rather than relying on TeX constructs and any particular font.
For example:
\useMPlibrary[mat]
\definemathstackers
[mp]
[alternative=mp]
\definemathextensible [mp] [leftarrow] ["2190]
\definemathextensible [mp] [rightarrow] ["2192]
\definemathextensible [mp] [leftrightarrow] ["2194]
\definemathextensible [mp] [longleftrightarrow] ["27F7]
\definemathextensible [mp] [rightoverleftarrow] ["21C4]
\definemathextensible [mp] [underbrace] ["FE3DF]
\setupbodyfont [dejavu-condensed,12pt]
\starttext
$\rightarrow{≠a}$
\stoptext
Furthermore, the MP arrow can be tuned
\startMPinitializations
ahlength := .5EmWidth ;
ahvariant := 1 ; % dimpled straight
\stopMPinitializations
as can line widths, etc.
Alan
